Austrian Defence

edit

The Austrian chess players Hans Haberditz (c. 1901–57), Hans Müller (1896–1971), and GM Ernst Grünfeld studied this defense, which was initially introduced by Italian chess player Alessandro Salvio in 1604. Black creates a lot of tension and aims to disrupt White's center and prevent white from seizing the initiative by mirroring White's moves, adding a little complexity to the position. This defence can be prone to equalizing quickly, if white doesn't know opening theory, but current theory suggests that white should gain a sizeable advantage with the appropriate moves.

White's responses

edit

White will probably reply with one of the following options:

  • 3. cxd5 - The classical main line in the Austrian Defence.
  • 3. dxc5 - Exchanging a central pawn for a flank pawn.
  • 3. Nf3 - Inviting a transposition to the Tarrasch Defence.
